Performance characteristics and Application: 
Super low formaldehyde cross-linking agent of textile wash and wear non-iron finishing, mainly applied in cellulose fiber and blended fabric, has good non-iron property. It also can be applied in  embossing, lightning, calendering and bubbling, as well as in shrink water finishing on full cotton and blended lining cloth.
Applied in low formaldehyde resin finishing of denim fabric, resistance of washable. Can improve fabric wash fastness, meanwhile doesn't much affect on fabric breaking strength / tearing strength.
RG-220B has very high reactivity, free formaldehyde content is very low, can comply with the requirement of "K-Tex standard 100"
(Class 11), free formaldehyde content is less than 75ppm. Finished textile has a high hydrolytic stability, soft hand feeling, good durable for water cleaning and dry washing property.
 
Application Method:   

1. Firstly adjust the PH value of the require finishing fabric to

   PH value<6.5, and shouldn't deflect to alkali.

1.  Suggest the following recipe added to 2g/l of penetrating agent,

    Adjust the PH value to < 4.0-4.5 by citric acid / acetic acid.

1. Padded under room temperature, dosage of RG-220A pls refer to

  the following sheet:
 

Fabric	Cotton	Viscose	Polyester/Cotton	Polyester/Viscose
RG-220B	40-90	80-120	30-70	40-80
Mangle expression	70-80	80-90	70-80	70-80

 

1. Make Magnesium chloride as catalyzer is most suitable for kinds

  of fabrics.
  Dosage of catalyzer:amount to 15% of low formaldehyde resin,
  but not less than 8g/L ( number base on MgCl₂·6H₂O crystal).
 

1. Fabric after prebaked should baking under high temperature on the condition of 150ºC, 2-3 minutes or 170-175ºC, 60-30 seconds.

Notes:

1. Before use this product, fabric should be natural meta-acid, and

Has good permeability.

1. Fabric treated by this product can don't need after-wash process,

But after wash process can help to remove the residual reactant
of the surface, to make the fabric hand feeling be better.

1. Necessary Preliminary test was needed at any occasion before

production.


Package and Storage:
Package: 160kg plastic drum.
Avoid insolation and frozen, stored in a cool, ventilated place.
Shelf life is one year in 5-30ºC
If stored in a higher temperature, the appearance will tend to be yellow, but it will not affect the product effective and usage. It should be used up once opened the drum. If didn't use up, then must seal it.
In rare cases, there will be little crystal separated out under low temperature. If increase the temperature or add water and stir, the crystal can be dissolved.
